Not even just Evans, but I am sold on the entire cast, especially Bucky. I only ever saw that actor in Hot Tub Time Machine and wasn't very impressed (mainly because of the character and the movie in general) but those photos and the trailer, he looks totally bad ass. They are definitely thinking about Winter Soldier further down the line. It's like when we knew Rhodey was in IM and everyone was like "But will he ever be War Machine?!?" and Marvel essentially just winked and gave a knowing smile. I definitely have a feeling we'll see him in later movies.
